SELECTIVE STIMULATION TO MODULATE THE SYMPATHETIC NERVOUS SYSTEM
First Claim
Patent Images
1. A method of modulating a neural pathway in the sympathetic nervous system, comprising:
- positioning at least one electrode of a lead in close proximity to a dorsal root ganglion upstream of at least one ganglion of the sympathetic nerve chain; and
providing energy to the at least one electrode so as to neuromodulate the dorsal root ganglion in a manner that influences a condition associated with the at least one ganglion of the sympathetic nerve chain while excluding neuromodulation of an associated ventral root.

Abstract
Systems, methods and devices are provided for the targeted treatment of a variety of medical conditions by directly neuromodulating a target anatomy associated with the condition while minimizing or excluding undesired neuromodulation of other anatomies. Typically, the target anatomy includes one or more dorsal root ganglia, dorsal roots, dorsal root entry zones, or portions thereof. Such target stimulation areas are utilized due in part to their effect on the sympathetic nervous system.

15. A method of modulating a portion of a neural pathway in the sympathetic nervous system, comprising:
-
positioning at least one electrode of a lead in close proximity to a target dorsal root ganglion associated with the portion of the neural pathway; and energizing the at least one electrode so that the portion of the neural pathway is altered and energy provided by the at least one electrode dissipates within the target dorsal root ganglion while excluding an associated ventral root. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
